Definitions
- the present invention relates to carboxamide-substituted pyrazoles and tri(hetero)aryl pyrazoles, pharmaceutical formulations containing such compounds, processes for manufacture and the use of such compounds in methods of reducing the heart rate and, accordingly, for its use in methods of treating and/or preventing cardiovascular diseases and/or cardiovascular comorbidities, which are exacerbated by an increased average 24-h heart rate of ⁇ 90 beats/min.
- bpm cardiovascular diseases selected from the group comprising cardiac arrhythmia (hereinafter CA), hypertensive heart disease (hereinafter HHD), tachycardia, inappropriate sinus tachycardia (hereinafter IST), angina pectoris (hereinafter AP) and stable angina pectoris (hereinafter SAP), myocardial ischemia (hereinafter MI), coronary artery disease (hereinafter CAD), heart failure (hereinafter HF), and stroke, as well as cardiovascular comorbidities selected from the group comprising diabetes, metabolic syndrome, obesity, and chronic kidney disease (hereinafter CKD) in humans and/or animals.
- CA cardiac arrhythmia
- HHD hypertensive heart disease
- IST inappropriate sinus tachycardia
- AP angina pectoris
- SAP stable angina pectoris
- MI myocardial ischemia
- CAD coronary artery disease
- HF heart failure
- stroke as well as cardiovascular comorbidities selected from the group comprising diabetes, metabolic
- CVD Cardiovascular diseases
- CVDs are a class of diseases that involve the heart and/or blood vessels.
- CVDs generally include coronary artery diseases (CAD(s)) such as AP and myocardial infarction (also known as heart attack).
- CAD(s) coronary artery diseases
- Other CVDs are inter alia CA, HHD, IST, AP and SAP, MI, HF, and stroke.
- CVDs may vary depending on the disease concerned. For instance, CAD and stroke involve atherosclerosis. This may be caused by high blood pressure, smoking, diabetes, lack of exercise, obesity, high blood cholesterol, poor diet, and excessive alcohol consumption, among others. Of note, high blood pressure results in 13 % of CVD deaths.
- CVDs involving the blood vessels are known as vascular diseases and are reflected by inter alia CAD, peripheral arterial disease (disease of blood vessels that supply blood to the arms and legs), cerebrovascular disease (disease of blood vessels that supply blood to the brain, including stroke), renal artery stenosis, and aortic aneurysm.
- CVDs that involve the heart are reflected by cardiomyopathy (diseases of cardiac muscle), HHD (diseases of the heart secondary to high blood pressure or hypertension), HF, pulmonary heart disease (a failure at the right side of the heart with respiratory system involvement), cardiac dysrhythmias (abnormalities of heart rhythm).
- cardiomyopathy diseases of cardiac muscle
- HHD diseases of the heart secondary to high blood pressure or hypertension
- HF pulmonary heart disease
- cardiac dysrhythmias abnormalities of heart rhythm
- Dyslipidemia is associated with more than half of all cases of ischemic heart disease globally. About 17 million deaths occur worldwide each year from CVD. About 26 million people worldwide suffer from HF, accounting for 1 % - 2 % of healthcare resources in industrialized countries.
- full treatment goals are not met with current therapeutics, such as beta blockers, angiotensinconverting-enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), and diuretics in all HF patients.
- Heart rate is an important contributor in the pathophysiology of CVDs, as e.g. in case of CAD and HF, and is being increasingly recognised as a modifiable risk factor in respective patients.
- Heart rate is determined by spontaneous electrical pacemaker activity in the sinoatrial node (hereinafter SAN). Cardiac pacemaker cells generate the spontaneous slow diastolic depolarisation that drives the membrane voltage away from a hyperpolarised level towards the threshold level for initiating a subsequent action potential, generating rhythmic action potentials that propagate through the heart and trigger myocardial contraction.
- the rate of spontaneous diastolic depolarization is significantly influenced by l f , a mixed sodium-potassium current involving ion movement across the so-called f-channels, which are activated by hyperpolarization, and the opening of which is dependent on the intracellular availability of cyclic adenosine monophosphate.
- the l f current is thus an ionic current that determines the slope of the diastolic depolarisation, which in turn controls the heart rate.
- the cardiac impulse originates in the SAN, located at the right atrial endocardium, between the upper and lower cava vein, and formed by highly specialized cells that are able to generate action potentials, which start the sinus rhythm.
- phase 4 is characterized by a slow increase in membrane potential to the threshold for triggering a new action potential.
- currents both inward and outward involved in the functioning of the SAN, able to determine the profile of the final current.
- the three main ones are:
- the funny current i.e. l f
- the funny current is highly expressed in spontaneously active cardiac regions, such as the SAN, which is the natural pacemaker region, the atrioventricular node and the Purkinje fibres of conduction tissue.
- the funny current is a mixed sodium-potassium current that activates upon hyperpolarization at voltages in the diastolic range (normally from - 60/- 70 mV to - 40 mV).
- the membrane When at the end of a sinoatrial action potential the membrane repolarizes below the l f threshold (about - 40/ - 50 mV), the funny current is activated and supplies inward current, which is responsible for starting the diastolic depolarization phase.
- the funny current controls the rate of spontaneous activity of sinoatrial myocytes, and hence the cardiac rate.
- HCN hyperpolarization-activated cyclic nucleotide-gated channels family
- Kv voltage-gated K +
- CNG CNG channels
- HCN channels are a family of six transmembrane domain, single pore-loop, hyperpolarization activated, non-selective cation channels.
- HCN4 is considered the main isoform that is able to control the heart rate.
- HCN4 channels may be coupled to rhythm disturbances, which have been already reported in humans.
- an inherited mutation of a highly conserved residue in the CNBD of the HCN4 protein (S672R) is associated with inherited sinus bradycardia.
- a missense mutation (S672R) on the exon 7 in hHCN4 gene induces the production of an isoform of the pacemaker channel changed at cAMP binding site level, which was responsible for a familial form of an asymptomatic bradycardia.
- l f generates spontaneous activity and modulates cardiac rate.
- activation is the key process in the modulation of rate by autonomic transmitters.
- the mammalian pacemaker region (SAN) is densely innervated by the autonomic nervous system: sympathetic ß-adrenergic stimulation accelerates, and parasympathetic muscarinic stimulation slows cardiac rate.
- l f inhibition may lead to slowing down cardiac rate.
- pharmacological reduction of heart rate is a crucial target in the treatment of several pathological conditions characterized by a deficiency of oxygen supply to the working myocardium, such as AP, a common manifestation of CAD, MI and HF.
- HTN4 heart rate-inhibiting agents
- cardiovascular diseases selected from the group comprising CA, HHD, tachycardia, IST, AP and SAP, MI, CAD, HF, and stroke
- cardiovascular comorbidities selected from the group comprising diabetes, metabolic syndrome, obesity, and CKD in humans and/or animals.
- ivabradine a new molecule selected for higher funny channel selectivity and reduced side effects, has been developed and is now being marketed for pharmacological treatment of chronic stable angina. Ivabradine is currently already used as a treatment option for SAP and HF in patients.
- Ivabradine is a pure heart rate lowering agent acting by inhibiting the funny current (l f ) in the SAN.
- Ivabradine is thus selective for the l f current and exerts significant inhibition thereof and heart rate reduction at concentrations that do not affect other cardiac ionic currents. Ivabradine lowers heart rate without any negative inotropic or lusitropic effect, thus preserving ventricular contractility. Ivabradine does not affect blood pressure, myocardial contractility, intra-cardiac conduction, or ventricular repolarisation.
- Efficacy of ivabradine in four patients with inappropriate sinus tachycardia a three month-long experience based on electrocardiographic, Holter monitoring, exercise tolerance and quality of life assessments.
- Kaplinsky E1 Comes FP, Urondo LS, Ayma FP; Heart Rhythm. 2010 Sep;7(9):1318-23 .
- ivabradine is generally well tolerated, patients may still complain of side effects, such as visual symptoms and bradycardia.
- ivabradine is contraindicated in severe bradycardia, II or III degree atrio-ventricular block, ejection fraction ⁇ 35%, and severe hypotension.
- CYP 3A4 inhibitors such as ketoconazole, macrolides (such as erythromycin), and nefazodone (used in the treatment of human immunodeficiency virus).
- beta blocking medication or calcium antagonists are still routinely administered prior to computer tomography coronary angiography (CTCA) examinations.
- CTCA computer tomography coronary angiography
- Ivabradine appears to be an alternative, but still provides for the above-mentioned side effects.
- the use of beta blockers, calcium antagonists, or ivabradine is limited, however, due to various contraindications. In recent studies, for instance, a substantial portion of patients requiring heart rate reduction has contraindications to beta blockers.

- the first step is a condensation reaction of compound 2a with the second key starting material compound 3a.
- the hydrazone intermediate compound 4a is formed at ambient temperature, but the formation of compound 5a out of compound 4a occurs at elevated temperature.
- the reaction mixture needs to be heated by slow rate heating.
- Compound 2a reacts rapidly with compound 3a, resulting in a condensation product, which is not purged in the subsequent reaction steps.
- the resulting pyridyl-aryl-pyrazole ester compound 5a is a mixture of the methyl and ethyl ester which is not isolated, but converted to the corresponding carboxylic acid compound 6a using an aqueous sodium hydroxide solution.
- the product compound 6a precipitates out of solution and can be isolated in solid form.
- the addition of hydrochloric acid solution needs to be monitored on pH, as reaction mixture needs to be of pH ⁇ 2.
- the obtained dry compound 6a can be used without further purification in the next process step.
- Step 2a alternatively, compound 6a could also be isolated as either oxalate or hydrochloric acid adduct.
- the oxalate adduct can be prevented by isolating intermediate compound 2a in solid form by filtration. This filtration step purges all remaining diethyl oxalate, which is the source of the oxalate anion.
- a hydrochloric acid adduct formation can be prevented.
- Step 3 This process step describes the synthesis of compound 8a starting from the GMP starting material compound 6a (see Scheme 13 below).
- the intermediate acid chloride compound 7a is not isolated, but the process is performed as a two-step one pot reaction.
- the product is isolated in solid form, and used without further purification in the next process step (see below).
- This reaction is conducted with oxalyl chloride at ambient temperature. Preferably, slow dosing of said reagent oxalyl chloride is performed.
- the N,O-dimethylhydroxyl amine is added as its HCl salt. No reaction should occur, until this reagent is liberated by dosing of the base.
- the preferred base with the context of the present invention is diisopropylethylamine (DiPEA).
- Step 4 This process step 4 describes the synthesis of compound 9a starting from the Weinreb amide compound 8a (see Scheme 14 below).
- Compound 9a is isolated as a solution in THF. This solution can be used in the next step of the synthesis without further purification.
- the reagent methylmagnesiumchloride can be commercially obtained as a tetrahydrofuran solution (22 %-wt active material). This solution can be transferred directly from the pressurized container into the reactor.
- Step 5 Process step 5 is characterized by the synthesis of compound 10a starting from the ketone derivative compound 9a, which is harvested as a tetrahydrofuran solution (see Scheme 15 below).
- a sodium ethoxide as 21 %-wt solution in ethanol is used for the GMP synthesis of compound 10a .
- Step 6 The synthesis step 6 describes the synthesis of compound 12a starting from the intermediate compound 10a (see Scheme 16 below).
- the chemistry is a two-step process in which first a keto-imine (i.e. compound 11 a) is formed, which is not isolated, followed by a Mannich reaction yielding the compound 12a. In both steps the solvent acetic acid is used. The ammonia donor is in both cases ammonium acetate. The paraformaldehyde is dosed as a solid to the reaction mixture, in order to minimize the required amounts of solvents.
- the first step is performed at approx. 45 ⁇ 5 °C, while the second step is performed at approx. 35 ⁇ 5°C.
- Dissolution of the process intermediate compound 11 a and the intermediate product compound 10a occurs at temperatures above approx. 30 - 35 °C.
- the product compound 12a precipitates out of solution by addition of ethanol to the reaction mixture.
- Step 7 describes the synthesis of compound A as crude product, starting from the intermediate compound 12a (see Scheme 17 below).
- the reaction mixture is heated and kept under pressure.
- a positive side effect of performing the reaction under pressure is the fact that the crude isolated compound A is of higher chromatographic purity.
- Step 7a Purification Isolation and release testing of compound A as crude product:
- the finalization of the synthesis process is characterized by two distinct purification steps.
- the first step describes the crystallization of the crude product compound A out of an acetic acid solution, using water as anti-solvent. This step is intended to remove organic impurities formed during the last steps of production, and reduce the amounts of compound 12a, if still present as impurity in the final product.
- Compound A can be also obtained as acetate adduct. The acetate adduct can be identified by its distinct XRPD pattern. Dosing water, however, yields compound A as a free base with the correct polymorphic form.
- the second step consists of dissolution of the purified compound A in a mixture of dichloromethane and methanol in order to perform a screening filtration designed to remove any foreign particles, if present.
- the product can be isolated by filtration after a solvent switch to methanol.
- Final release testing may also be performed.
